Tell me what's going on

Send a short email. Five things help me reply usefully:

1. Your name and the company.
2. Rough stage — people, revenue, last round if relevant.
3. The visible symptom you're seeing.
4. What you've already tried.
5. Anything else that gives me context.

I read every message myself and reply within two business days. If we're a fit, the next step is a forty-five minute conversation.
